GENERAL INSTRUCTIONS

Adjuvant: Infinity Ultra requires the use of Hasten Spray Adjuvant or equivalent (e.g., Kwickin® Spray Adjuvant) to enable good uptake into weeds and to maximize efficacy. Where Hasten is recommended in the Directions for Use table at a range of 0.5 – 1.0% v/v, the higher rate in some situations may provide faster speed of weed burndown and the level of final control may be improved in conditions such as cool, cloudy weather, weak crop competition, or less than optimal spray coverage. The use of non-ionic surfactants, paraffin-based adjuvants, or plant-based oils with lower loading of active ingredient may result in a significant loss of efficacy. However, where Hasten 0.5% v/v is recommended in the Directions for Use table then Loveland Products MSO with Leci-Tech® at 1.0% v/v can be substituted.

Recommended crop growth stage: Wheat, durum wheat, barley, oats, and triticale should be a minimum 2 leaf stage (Z12 growth stage) before application of Infinity Ultra. DO NOT apply after commencement of stem elongation (Z30). Although Infinity Ultra may be applied to crops up to growth stage Z30, weed control is generally optimized when Infinity Ultra is applied to young crops before shading of weeds occurs from advanced, dense crop canopies. Optimum results are achieved when sprayed 4 – 6 weeks after sowing when cereals have usually 2 leaves to 2 tillers (Z12 – Z22).

Agronomic and environmental factors: DO NOT apply to crops undersown with legumes. Some crop yellowing or bleaching can be expected following application of Infinity Ultra. These effects are transient and only impact leaves present at application and do not affect crop development or grain yield. DO NOT apply if crop or weeds are not actively growing or stressed due to, for example, cold or dry or excessively moist conditions, disease, previous herbicide or foliar fertilizer treatment as crop damage may be more severe and/or reduced levels of weed control may result.

Efficacy: For optimum weed control from Infinity Ultra, complete and even coverage of all target weeds is essential. Results are best when applied under good growing conditions and with thorough coverage of weeds. Application to weeds or crop under stress may result in reduced weed control and should be avoided. As weed and crop densities increase, water volume and rate of Infinity Ultra may also need to be increased where this is indicated.

Compatibility: For advice on the compatibility of products not listed below, contact the manufacturer, Bayer Crop Science. When tank mixing Infinity Ultra with other products always observe the directions for use and plant back restrictions on the Infinity Ultra label and the label of the tank mix partner.

Crop safety and compatibility in oats: Oats are more sensitive to Infinity Ultra than wheat, barley, or triticale, and crop effects may be more pronounced and remain visible for longer periods of time. Avoid spraying oats during periods of frosty weather or if frosts are imminent or may follow for some days after application as excessive damage in terms of biomass reduction may occur. Do not tank mix with bromoxynil (e.g., Buctril 200 EC, Bromicide 200) or metribuzin (e.g., Mentor WG Herbicide) products when applying to oats as excessive damage may occur. Infinity Ultra (at 110 mL/ha plus Hasten at 1% v/v) applied to oats is biologically compatible with MCPA LVE 570 at up to 440 mL/ha.

Compatibility in fallow: Satisfactory performance requires the use of high-quality glyphosate products from reputable manufacturers.

Crop rotation recommendations: Minimum re-cropping intervals apply for all crops following application of Infinity Ultra to minimize the risk of damage to following crops. However, environmental and agronomic factors make it impossible to eliminate all risk and therefore the potential for damage to following crops remains. The safety of following winter crops planted with disc seeders has not been evaluated. Infinity Ultra breaks down by microbial degradation, which is favored by warm, moist, aerobic soil which has adequate levels of organic matter (> 2%). Soils low in organic matter will slow microbial degradation. Rainfall or irrigation less than what is described in the following tables will result in extended re-cropping intervals. Conditions that don’t support microbial activity such as patchy, light rainfall with extended dry and/or cold periods may also result in extended re-cropping intervals. Rainfall or irrigation occurring late in the re-cropping interval will result in an extended re-cropping interval. Re-cropping intervals following application of Infinity Ultra to soils with little or no ground cover has not been fully tested and may require longer re-cropping intervals and/or greater interim rainfall. Vegetation such as crop or weeds provide a barrier to intercept Infinity Ultra from reaching the soil as well as importantly providing a canopy to aid microbial degradation by maintaining a moist micro-climate.
